Hi Mike,
Even if you drag the pins, they will not stay where you drag them to - the next time the map is loaded it will return them to the original locations.
That being said - if you want to eliminate the ability for a user to drag the pins, your best bet is to recreate the map to load in KML/KMZ instead of JavaScript. Here's the deal...
In the last step of the map creation process (step 5) you have a choice with regard to the way in which your map will load. If you choose "via KML/KMZ" your pins will be static (the user will not be able to drag/drop them). If you choose JavaScript, the user will be able to move the pins.
Hope this helps!
